<p>Reports cases when <code>except</code> clauses are not in the proper order,
  from the more specific to the more generic, or one exception class is caught twice. </p>
<p>
  If you do not fix the order, some exceptions may not be caught by the most specific handler.
</p>
<p><b>Example:</b></p>
<pre><code>
try:
    call()
except ValueError:
    pass
except UnicodeError:
    pass
</code></pre>
<p>The IDE recommends moving the clause up. When the quick-fix is applied, the code changes to:</p>
<pre><code>
try:
    call()
except UnicodeError:
    pass
except ValueError:
    pass
</code></pre>
